The first part of the movie is better than the latter, with the humorous antics of the title character, and the excellence of his sidekick, not least of which is the coffee-making. The lead villain is also fun to watch, especially with his the constant (and humorous) concern of the fearsomeness of his image/presence. The split-screen moment, where various bounty hunters are sent for the title character, is amazing, and among the most innovative visuals I've seen in movies yet.
Sadly, the movie gets a little annoying when this title character stops being funny (and ungrateful), starting with the moment he shoots the sidekick. There is also unexplained physical prowess, the sort that makes the movie feel like passive entertainment, and the destruction that happens in the movie's final action sequence is way too much. Why the noise?
